APPARATUS FOR INDIO ATIHG TIDE LEVEL OF PETROL PETROLCON'IJAH-IEE OF I MOTOR-CARS AND THE LIKE.

Application filed June 14. 1907.

To all iii/tom it may concern:

Be it known that I, Fnncmncn IIIIPIEN nocnnn. a citizenct' the (lcrman Empire. residing at Iintertiirkheim-Stuttgart, in the Kingdom of \Yiirtemherq. Empire of Germany, have invented certain new and useful Improvements in Apparatus for Indicating the Level of letrol in the l-etrol-(lontainer oi Motor-Cars and the Like, of which the following is a description, reference being and to the letters and figures of reference marked thereon.

This invention relates to an apparatus serving for indicating the level of the petrol in petrol tanks and more particularly adapted for use with motor cars.

The apparatus consists snhstantially ot a float. which is immersed in the petrol and transmits to a spring controlled visible index or pointer the increase or diminution of the petrol, the pointer indica ting on a scale the levelo't' the contents of the tank. A person using sitch an apparatus on a. motor car can not only visibly and constantly inform him-- self of the quantity of petrol in stock even while the car is running, hut can also ascertain and check or control the consumption during the journey in the simplest way. Protection is also afforded by, the apparatus constituting the present invention, which cannot be tampered with from the outside, against the unauthorized witlnlrawal of pe had to the accompanying drawirn trol from the container, while the motor car When the tank is refilled j with petrol the float is lifted by the latter,

is in a garage.

Specification of Letters Patent.

In order to prej inside the petrol tank and is provided with pro ections with which it rests against the &

walls of the tube, so that adhesion thereto or rattling thereon is prevented.

The object of this invention is shown in one form of coi'istruction. as an example. in theaccompanying drawings, in which.

Figure I. is a sectional. front view of the Patented Nov. 24, 1908.

Serial No. 379,030.

petrol container; Fig. 2, a front view of the indicating device on an enlarged scale; Fig. 3, a side view of Fig-2 in axial section; Fig. 4. a plan view; while Fig. 5 is a. view show ing the. relative relation of the spring to the case and spindle.

The apparatus according to this invention has a spiral spring 1/ of watch spring type. one end of which spring is fast while its other end is connected with a small wheel I) which is mounted on a spindle (r. The spindle c is supported in hearings in a suitable case and is revoluhle and carries an index or pointer (1 which moves over a suitable scale 0. the division ol. which corresponds for in stance to the liter contents of the petrol container f. A cord or the like is provided which is connected with th'e'small wheel I).

and runs over the same, on which cord at float /i. is suspended which is innnersed in the petrol. In order to prevent oscillation of the float l1 vhen the car is running. it is guided in a tube 17 which coi'mnunicates with the petrol container f, while by the arrangement of longitudinal projections /s on the float ll, it. is prevented adhering to the tube 1' as it only comes in contact with it at a few points. Finally a sieve I is provided at the bottom of the guide tube 1' which prevents the penetration of bodies into the guide tube 2'. so that jamming of the float /L is thereby prevented and its reliable working insured.

I declare that what I claim is:--

In a device of the class described. a closed tank; a vertically arranged t'uhe depending from the top wall of said tank and open at its bottom; a casing c vlindi"ical in Form and having a tangentially arranged inlet secured to the top wall of said tank and in communication with said tuhc: a horizontally arranged spindle having hearings in the end walls of said casing; a grooved wheel within said casing and mounted upon said spindle: a spiral spring within said 'asing having its ends attached thereto and to said spindle: a pointer carried by said spindle; a cord attached to said grooved wheel and extending through the tangei'itial inlet leading into said casing; a. fieat attached to said 00rd and adapted. to meve 1n sale tube; and mojections upon said. float "t0 engage the m- Y n F H I\I G ner surl ace of sand tube as the float moves RIEDRIQ HUTTE HER therein, the relatlve arran 'ement oi the Witnesses:
